THREAD GUARD FOR SPINNNG .AND TWISTING FRAMES.

Application filed September 25, 1925. Serial No. 58,615.

This invention relates to the art of spinning and has particular reference to an im- Jrovement in spinning or thread-twisting frames of the ring type.

One of the outstanding objects of the.

present invention is to provide an improved thread guard consisting of means interposed between adjacent bobbins which effectually functions to pievent, in event of breakage of the thread, the free end of the brol-:en thread of one bobbin from coming into contact with the next adjacent bobbin.

The invention furthermore comprehends a thread guard of the character set forth which includes means for mounting the same upon the frame, whereby retraction thereof from between fected for the purpose of facilitating the ty-y the bobbins may be readily efin view,

reference is had to the following specication and accompanying drawings in which there is exhibited one example or embodiment of the invention which is in no way intended as a limitation uponthe scope of the appended claims as it is to be clearly understood that variations and modifications which properl y fallwithin the scope of said claims may be resorted to when found expedient.

Referring to the drawings by characters of reference, a substantially common form of spinning or thread-twisting frame is illustrated` including end headers A and B connected by the box rail C and provided with a' suitable number of middle frame members or samsons D. The spindles E for supporting the bobbins F are mounted in the usual manner in longitudinally spaced parallel relation upon the box rail C and are driven by the whorls Gr from the driving cylinder H. The builder rail I formed with apertures to accommodate the bobbins and having therings J and travelers K, is raised and lowered in the usual manner'by the lifter rods L, through the medium of the cam M and builder mechanism. The guard means constituting the present Vinvention and designed as an attachment, for the spin ning frame, consists of a plurality of guard blades 10 mounted in such a manner as to be disposed between the adjacent bobbins F, whereby in event of breakage of one of the threads leading from the spools N to the bobbins, the loose end of thebrolren thread 1 on the bobbin will be prevented from conthe builder rail.

mounted for horizontal sliding movement in the guides lll. The rack sections l?) are slid forwardly and rearwardly by v"meansot the pinions l5 which mesh therewith and which are keyed to a shaft i6 journaled in the headers Aand B.` The shait extends beyond said headers and has connected therewith manipulating hand wheels 17| and 18, the former being provided with a peripheral radially projecting lug 18 engageable with a stop or abutment 19 on the header A to limitfthe sliding movement ot the pinions and guard bar in their opposite-directions. In order to accomnjiodate the guard-blades l() when in their 'forwardly disposed active position betweenV the spindles andbobbins E,-

theibuilder `rail is slotted torwardvifrom its rear edge at 21. This permits` of the disposition ot the blades l0 between adjacent bobbins while allowing for vertical reciprocatory movement oit the builder rail.`

In A`view of the tact that the crowt'eet O carried by the llit'ter rods L are each provided with a pin P projecting upwardly through an aperturer Lin the litter "rail, the guard blades l()a which aline therewith must ot necessity `be ot lesser width than the remaining guard blades in order to olivi-ate interference with the pins l). In order, therefore, to compensate tor the decrease in width ot' the'biades 10a, stationary front blade sections lOlare provided by supporting standards 22 carried by the box rail and extending upwardly through apertures-23 in Fromthe foregoing it will thus be seen that a thread guard'has been devised as an attachment 'for a spinningor thread-twisting frame, which consists olf a `plurality ot guard'blades disposed between adjacent bobbins and spindles whereby in eventotbrealage of 'the thread leading to the bobbins from the spindles, a means is aiiorded tor VpreventingY thev `tree end ot' the broken Vthread on one b'obbin from flying loose and either picking up oil and splashing the thread ot' an adjacent bobbin or becoming entangled therewith. It is furthermore obvious that in order' to facilitate the tying of `broken threadsor the removal and application ot the bobbins to the spindles, said guard blades aremounted for rearward vmovement. to allow for their retractiont'rom their active positions between the spindles? such y i movement being accomplished by manipulation oit' the hand wheels *i8* arranged at either end ofthe frame.'

As illustrated, by way ol example, .the blades 10am' connected to the guard bar-ll by `inserting-therearends ot the blades` in the notches or recesses 24 formed in the front face of the bari-l, and by locking thesame in place4 through the `inefdiumi ofi-a, jamb block 25, which is retained and `niged in-a clamping direction by y virtue of ai conicalmovable sections, and means headed screw 26. The guard bar l1 is also preferably adjustably secured to the hangers l2 bya screw 27, which passes through a horizontal slot'28 in each end of the bar 11. rlhis permits of a shitting olf'v the guard bar towdispose the blades Centrally oteach slot 2l`so as to prevent'contactor trictional engagement of the; blades with the edges of the material defining the slots.

lh'om the foregoing it is apparent that a thread guard tor spinning or thread-twisting trames, has been devised,` which is ei:- tremely simple, comparatively inexpensive to vmanutac/turc and attach, and which is highly elhcient in its purpose;

that is claimed is: i Y
